feat: Tool from OpenAPI spec

[hughlv]

Currently each tool is a python function. We can expand this to OpenAPI spec so no code is required at all.

The solution could be either generating a python function from the json/yaml, or perform a dynamic request at runtime. API key should be handled properly.
